EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.6 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 87% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

Network-AI is a TypeScript/Node.js multi-agent orchestrator. Prior to version 5.4.5, the MCP SSE server defaults to an empty secret (process.env['NETWORK_AI_MCP_SECRET'] ?? '' at bin/mcp-server.ts:89), which causes _isAuthorized (lib/mcp-transport-sse.ts:254) to return true unconditionally for every request — no Authorization header is required. Simultaneously, _handleRequest sets Access-Control-Allow-Origin: * (lib/mcp-transport-sse.ts:272) on every response, so a cross-origin browser fetch can read the result without restriction. An unauthenticated attacker who can lure a user to a malicious web page can invoke all 22 exposed MCP tools — including config_set, agent_spawn, and blackboard_write — against a default-configured localhost server. Version 5.4.5 patches the issue.
